Dear Brian , 

 Thanks for your scholarly answers, but no psychological. I mean here is communication science and not the psychology of communication! especially interpersonal communication. As you know, communication theory included an interdisciplinary field. According to the definition of Dainton,  Zellei & et al. (2011): 

"Communication theory is a field of information theory and mathematics that studies the technical process of information and the process of human communication."

For more detailed information, see:

Axiology is concerned with how values inform research and theory development. Most communication theory is guided by one of three axiological approaches. The first approach recognizes that values will influence theorists' interests but suggests that those values must be set aside once actual research begins. Outside replication of research findings is particularly important in this approach to prevent individual researchers' values from contaminating their findings and interpretations.

Rhetorical: views communication as the practical art of discourse.

Semiotic: views communication as the mediation by signs.

 Phenomenological: communication is the experience of dialogue with others.

 Cybernetic: communication is the flow of information.

Socio-psychological: communication is the interaction of individuals.

Socio-cultural: communication is the production and reproduction of the social order.

 Critical: communication is the process in which all assumptions can be challenged.
